Study of
Sea Level Change in the Northeastern U.S. Using
GPS & Tide Gauge Data with Applications to
Global Sea Level Change

Changes in sea level can
reveal much about our environment. But what if the
devices used to measure that level are being influenced
by such effects as crustal motion? To determine if this
is the case, we are using GPS data to compute vertical
velocities at tide gauge locations. Coupling this
information with height data should generate a more
accurate rate of sea level rise, particularly in areas
where rates differ significantly from the global average.

The principle objective of this
study is to use Global Positioning System (GPS),
absolute gravity, and tide gauge measurements to
improve global data related to sea level change.

In addition, the information from
this project will improve the current models of
glacial isostatic adjustment (GIA).
